New model by Carrera For Fun: a Zeppelin!

The Real Thing

The Goodyear Blimp is the collective name for a fleet of blimps operated by Goodyear Tire and Rubber Company for advertising purposes and for use as a television camera platform for aerial views of sporting events. Goodyear began producing airship envelopes in 1911 and introduced its own blimp, The Pilgrim, in 1925.The blimps are filled with helium. The helium is maintained under low pressure, so small punctures do not pose serious consequences for the blimp. In fact, one inspection element of the blimps is to look into the envelope for pinpoints of light which are indicative of small holes. The blimps have infrequently been hit by small-arms fire from the ground.[citation needed] Also, birds can hit blimps and make small beak holes. These incidents have not resulted in any serious consequences to the blimp or its crew.The Goodyear blimps are non-rigid (meaning their shape is not maintained by a rigid internal structure) dirigibles (directable/steerable airships). However, the term dirigible is seldom used in connection with blimps, being associated more with the great rigid airships of the past. Inside their exterior envelope, the Goodyear blimps are equipped with gas bladders. As the blimp ascends or descends, the internal bladders expand or contract to compensate for density changes and to maintain uniform pressure in the envelope. - Wikipedia
